INFORMATION ABOUT OVERHAULING
8.2.3 4-cylinder camshaft housing check
The camshaft housings only contain the timing system side
bushing Q.
Use an internal dial gauge to measure the diameters of housings
X - W - K - Y - Z.
With a micrometer, measure the diameters of gudgeon pins
X1 - W1 - K1 - Y1 - Z1 (Fig. 8.4).
According to the values measured, calculate the clearance
between the housing and gudgeon, which is to observe the
values in Tab. 8.2a.
The MAX value of wear allowed is 0.120 mm.
Important
• Tab. 8.2a details the dimensional values of new components
only.
